“We can’t say enough great things about our experience with Keystone Decks. From the initial meeting to the final cleanup, they were amazing to work with and we can’t be happier with our deck project. During the proposal phase, the team provides detailed images so you can see EXACTLY what the finished project will look like. The crew led by Matt was professional, friendly, hard-working and provided great communication the whole time. Keystone will not be the lowest estimate you receive, but we can attest that the quality is beyond the price and worth every penny. We are thrilled with our new deck and pavilion! And we are happy to be a reference for anyone who has questions.”
